In the 2 yrs I have been employed our machines have alway been cans with the exception of the small water bottle.  And no one is allowed to have anything but water on the floor.  However, if you work in the cash office, invoicing, claims, personnel you may drink whatever you choose as long a it is non-alcohol.  Any comments?

By the way: our pop machines only work half the time.  The rest of the time they are either jammed with change or empty.
